Description

Antibacterial Ondol Floorboard {A Floor Board And The Method For Protection Of Germ}

The present invention relates to an antibacterial ondol floorboard, which suppresses and sterilizes growth and growth of microorganisms such as molds and bacteria, and relates to floorboards that are harmless to human beings.

There are hundreds of thousands of microorganisms found on the planet, and they are scattered all over the earth and grow wild and parasitic. In particular, mold is harmful to everything from household goods to industrial products.

That is, it grows and grows internally and externally inside and outside of the building, and it damages the aesthetics and aesthetics of the building. It also causes and infects people and livestock such as bronchial asthma, allergic syndrome, fungal poisoning, and fungal infections. The damage caused by mold, such as deterioration and deterioration of foods and medicines, and material and performance of various industrial products, varies.

These molds are sealed, humid, and high temperature, which makes them a good environment for breeding, and the indoor environment in which we live is a breeding ground for breeding, causing foul headaches, skin disorders, as well as dirty smells. Deterioration of the gypsum board material, and at the same time there is a problem such as shortening the life.

Ondol floorboards, which are being constructed in recent years, are made of wood, and moisture is absorbed and moisturized, making them easy to grow as a natural habitat of molds.

In order to solve this problem, the sterilizing material may be sprayed, but the scattering of the sterilizing material may damage the human body or the livestock, and the effect may be a temporary problem.

In addition, it is used as a building material by coating a coating containing a bio-ceramic powder that emits far infrared rays and an inorganic antimicrobial agent having an antibacterial function, but only the outer surface of the building material has its effect, and thus it is not a fundamental solution for being contaminated from the inside. It became.

The present invention has been made to solve the above problems, an object of the present invention is to provide a method for producing an ondol floorboard that is harmless to humans and livestock, and long-lasting, maintaining antibacterial against mold or bacteria.

In order to achieve the above object, the present invention is characterized in that the antimicrobial agent is treated with an antimicrobial agent, or mixed with an antimicrobial agent such as melamine resin, which is an adhesive for adhering veneers. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an enlarged cross-sectional view showing an embodiment of the present invention, UV coating (2) and veneer (3), antibacterial layer (4), adhesive layer (5), antibacterial layer (6), plywood (base plate) (7) and the antimicrobial layer 8 are joined to form an antibacterial ondol floorboard 1.

 To the plywood 7, 0.05 g to 10 g of a surfactant and 0.05 g to 20 g of an antimicrobial agent are added to 99.9 g to 80 g of water. In this case, when the ratio of the surfactant or the antimicrobial agent increases, the physical properties of the plywood itself and economical efficiency are increased. There is a problem, if less, there is a problem that the effect of dispersion and antimicrobial power is inferior.

The adhesive consisting of the adhesive layer (5) is made by adding and dispersing the antimicrobial agent 0.05g ~ 20g and the surfactant 0.05g ~ 10g to 40g ~ 90g melamine resin and 10g ~ 40g wheat flour.

Surfactants used in the above is a surfactant that can be easily dispersed, sodium dihexysul Fosuccinate, polyoxyethylene nonylphenyl ethyl, polyoxyethylene octylphenylethyl, polyoxyethylene lauryl Ethyl-based, polyoxyethylene cetylethyl-based, polyoxyethylene stearyl ethyl-based, and Triton X-100 (Triton x-100, Rohm & Haas), etc., are insoluble as an antimicrobial agent or hardly soluble in water, but are easily dispersed. 2-en-octyl-4-isothiazolin-3-one, diidomethyl-para-tolysulfone, 2-4-thiazolyl-benzimidazole, 2.3.5.6-tetrachloro-4 methylsulphonyl pyridine, methyl-2-benzi Imidazole carbamate (N-trich, methyl-2-benzimidazole carbamate) loromethylthiophthalimide, 3-iodopropynylbutylcarbamate, zinc-bis-2-pyridinethiol-1-oxide, and methyl-1- Butylcarbamoryl benzimidazol-2-yl carbamate is used (methyl-2-butyl carbamoyl benzimidazol-2-yl carbamate).

The ondol floorboard of the present invention consisting of the above materials, manufacturing process, and manufacturing method was subjected to the trial test as follows.
